1. A method of producing a porous hollow ceramic membrane comprising the steps of;

  • (a) providing a suspension of a particulate ceramic material having an average particle size greater than about 150 nm in a non-aqueous liquid;

    (b) electrophoretically depositing the particulate material onto an electrically conductive fibre core;

    (c) drying the fibre core-bearing the deposited material; and

    (d) sintering the fibre core bearing the deposited material at a temperature and for a length of time sufficient to combust the fibre core while producing a porous hollow ceramic membrane which has a density less than 95% of the density of the ceramic material.
